D)manual bilateral switching

Question

Quizplus · Accepted Answer

Unidirectional path switching and automatic protection switching are recognized methods for failure recovery in SONET (Synchronous Optical Networking). Unidirectional path switching involves rerouting the signal in one direction around a failure, while automatic protection switching is a mechanism that automatically switches to a backup path in case of a failure on the primary path.
